Structural change in pseudobinary nitrides containing AlN was predicted by using the structural map of AB compounds. According to the prediction, CrN shows the highest maximum solubility of AlN for transition metal nitrides with B1 structures. The predicted maximum solubility for CrN and TiN showed excellent agreement with those experimental results. It was indicated that the properties of pseudobinary nitrides such as hardness and anti-oxidation were improved with increasing AlN content, unless these nitrides changed from B1 structure to B4.
